From 43ae47011232c1e792d77e78db4a7d0ab05032be Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Tue, 3 Jul 2012 16:01:18 -0500 Subject: [PATCH] rbd: option symbol renames Use the name "ceph_opts" consistently (rather than just "opt") for pointers to a ceph_options structure. Change the few spots that don't use "rbd_opts" for a rbd_options pointer to match the rest.
